This is a followup to my earlier mail 'ksoftirqd using mysteriously high amounts of CPU time'. After working briefly with Andrew Morton on the issue we seem to have identified the 'pppoe' userspace program as the culprit for that issue.
After some playing with kernel options I switched my PPPoE connection options from asynctty to synctty, and observed almost no usage of ksoftirqd/0 at all, as it should be.
However, the pppoe process maintains an extreme amount of CPU utilization, cutting off the machines ability to send and receive at its fastest possible rate. Additionally the attached error fills dmesg after a couple of days (vanilla 2.6.3 kernel).
I'm hoping the PPP stuff in the kernel is well enough maintained that a problem/solution can be identified..
Thanks in advance!
Brad
